@dominikkukacka did you get the electron app working? I might be that you need to increase the GPU memory split on the pi. by default it is set to 16mb, probably best to bump it up to something like 256mb

Also I dont think electron currently works on the RPI1, so that could also be an issue

yeah, from what I understand they are ready to ship, but I dont know the specifics. I dont think it will be too difficult for resin to support, @agherzan can probably give a better estimate of the work involved
